Novel steel dam gate bottom shaft seepage-proofing and water-stopping device and construction method

Abstract

The invention discloses a novel steel dam gate bottom shaft seepage-proofing and water-stopping device and a construction method. The novel steel dam gate bottom shaft seepage-proofing and water-stopping device comprises a rack, wherein a pressing mechanism and a high-strength steel bar are arranged on the rack, a water-stopping steel plate is arranged at the bottom of a gate, and water-stopping rubber abutting against a gate fixing rotating shaft for sealing is arranged on the water-stopping steel plate; the pressing mechanism drives the high-strength steel bar to move, the water-stopping rubber is on the moving track of the high-strength steel bar, and the high-strength steel bar pushes the water-stopping rubber to be extruded and sealed with the gate fixing rotating shaft. The construction method comprises the following steps of S1, assembling a front water-stopping plate; and S2, installing the water-stopping rubber. According to the novel steel dam gate bottom shaft seepage-proofing and water-stopping device, the investment cost is low, the water stopping effect is good, and P-shaped rubber plays a dual water stopping role; construction is convenient, and potential safety hazards are small; the structure is simple, water sealing is tight and reliable, aging resistance is achieved, and service life is long; a pressing device further ensures the water stopping performance of a bottom shaft, and is easy to operate and convenient to maintain.

Description

technical field [0001] The invention relates to the field of steel dam gates, in particular to a novel steel dam gate bottom shaft anti-seepage and water-proof device and a construction method. Background technique [0002] Traditional water conservancy gates are subject to various restrictions on weight and lifting equipment, resulting in a small single hole width, coupled with the disadvantages of complicated opening and closing equipment, high cost, and difficult construction, which do not meet the requirements of modern urban water quality landscape planning. In this context, the steel dam gate was born in time, it opens and closes faster, the operation is easier, and it also overcomes the problem that the barrage is easily brittle and easily damaged, and has been widely used. During the construction of the steel dam gate, due to the working environment, the bottom shaft of the steel dam gate is in a state of flooding all the year round, which is a weak part for preventi...
